''Bart vs. The Space Mutants'' is the first LicensedGame for the [[UsefulNotes/NintendoEntertainmentSystem NES]] (also ported to the UsefulNotes/SegaMasterSystem, UsefulNotes/GameGear, UsefulNotes/SegaGenesis and numerous computers) based off ''WesternAnimation/TheSimpsons,'' developed by [[Creator/AbsoluteEntertainment Imagineering.]] The game revolves around Bart attempting to foil the space mutant's plan to power their world conquering machine by collecting random objects.

----

!! This game provides examples of:

* AmusementPark: The third level.
* BagOfSpilling: Bart leaves behind all of the tools he picks up after he completes a level. Sure, maybe the red spray paint might not be useful later on, but those cherry bombs and bottle rockets probably would have been.
* BossRemix: [[PlayingWithATrope Sort of]] -- the three boss themes are simply parts of the main theme repeated over and over. [[MostAnnoyingSound It gets really annoying after a while.]]
* CassandraTruth: [[AllThereInTheManual According to the manual,]] the reason Bart has to collect letters to get assistance in the {{Boss Battle}}s is because he's trying to get evidence to subvert this. Averted in the last level, where the other Simpsons are helping from the beginning.
* CollectionSidequest: The evidence.
* DamnYouMuscleMemory: Rather than the standard "A to jump, B to run / attack" style that most NES games use, this game has A use items and B controls both running and jumping. Performing a running jump involves a combination of both A and B in a fashion that is entirely unintuitive.
* DepthPerplexion: In certain places, you can stand on the horizon or "walk" along a river by jumping on the background. The game is highly inconsistent with this, even within the same screen. [[note]] It's really a 2D game with invisible platforms, flying enemies and backgrounds indistinguishable from the floor. The graphics do a good job at simulating depth though. [[/note]]
* DoomsdayDevice: The machine that the aliens are looking to power, although they don't reveal what it does unless Bart loses in the final level. [[spoiler: It mass produces robotic Homer duplicates.]]
* EasilyThwartedAlienInvasion: More or less lampshaded in the game. The aliens have a machine that can run on anything, but never think to fuel it with something already in abundance; instead they choose purple objects, or hats, and never think to look in more than one place for each item.
* EasterEgg: By firing a rocket at the "E" in the Kwik-E-Mart's sign, you get both an extra life and the game's SoundTest! Unfortunately, it only plays sound effects.
* EverythingTryingToKillYou: Including ''shoes'' and walking ''shopping bags.''
* GracefulLoser: The aliens prove to be this in the ending.
* IdiotBall: Some of Bart's methods of removing objects from the level are circumspect at best, yet they still work. One example is dropping towels off of a clothesline to cover up some purple toys in the first level -- the aliens never think to just pick up the towels.
* InvincibilityPowerUp: Jebediah Springfield's head, which is quite rare.
* MiniBoss: The alien man in the second level.
* NintendoHard: Bart can only take two hits before dying, and for the most part he has absolutely no way to actually fight the enemies.
* PassThroughTheRings: Near the end of the second level.
* PowerUpMount: Inverted -- the second time you see the RecurringBoss, he rides a giant shoe.
* RecurringBoss: Again, the alien man in the second level.
* RushmoreRefacement: Complete the game, and the space mutants add Bart's face to honor their WorthyOpponent.
* ShoutOut: Bart's x-ray glasses are generally considered a reference to ''Film/TheyLive.''
* SlidingScaleOfCollectibleTracking: This game uses "It's Here Somewhere."
* SmashingHallwayTrapsOfDoom: The second level has giant shoes which act as these.
* SomeDexterityRequired: The controls in this game is '''dreadful.''' Bart cannot and will not [[JumpPhysics execute a proper running jump.]] As a consequence, simple platform sections and obstacles become ''[[PlatformHell nightmarishly difficult]]'' to overcome.
* SoundTest: See EasterEgg.
* SpellingBonus: You can spell the names of other Simpsons characters to get their assistance with each boss.
* SummonMagic: You can summon Grandpa to give you coins with a whistle... Providing you stand one exact spot in the first level. Otherwise you'll just summon a dog to attack you.
** Using a donut in the last level summons Homer to act as a SmartBomb.
* SymbolSwearing: In the cutscene before the third level.
* TacticalSuicideBoss: The second boss drops suitcases, which you need to jump on in order to damage.
* TemporaryPlatform: The lollipops in the shopping mall are always ''visible'', but whether they can support Bart or not depends on their orientation.
* [[TokyoIsTheCenterOfTheUniverse Springfield Is The Center Of The Universe]]: A maximum of six people are working to stop the aliens (being generous and including Grandpa), and all of them in a single relatively isolated area. The aliens never think to simply move on to somewhere else or expand their search radius because ''it's a ''Simpsons'' game, you gotta attack Springfield.''
* TotallyRadical: The box.
* UnwinnableByMistake: It's almost impossible to clear the Museum without losing a life due to a section with very slow disappearing reappearing platforms that eats about 300 seconds off the timer.
